About Product
Perlite Filteraids are available in a full range of grades to meet the requirement of a wide variety of industrial applications from fast flow-rate to maximum clarity. Solubility of Perlite Filteraid is extremely low in inorganic and organic acids at both high and low temperatures. Solubility in alkali depends upon the kind of alkalies, the concentration and time and temperature of contact. Perlite Filteraids can filter out particles less than 1.0 micron in size
